Update Website Code To Be Compatible With PHP Upgrade

We're upgrading our site's PHP from 5.3 to the latest version. We want to ensure that our site will still function normally after this upgrade. Our site is a custom build and we'll need you to go through our code, determine what needs to be altered and make the necessary changes so that our site does not break when we migrate from our old PHP version. More details and our website will be provided in messages. Thank you.
